I think entering the following expressions just after starting SBCL will
allow development mixing libraries from user directories and from Guix
profiles:

--8<---------------cut here---------------start------------->8---
(require :asdf)
(asdf:clear-output-translations)
(asdf:initialize-output-translations
 '(:output-translations
   :enable-user-cache
   :ignore-inherited-configuration))
--8<---------------cut here---------------end--------------->8---

However with this configuration, the pre-compiled files in
"/gnu/store/..." will not be used at all; everything will be compiled
again if necessary and put in the user cache in ".cache/common-lisp/...".
